In the Netherlands, fertility clinics guarantee that a sperm donor will donate to a maximum of twelve women. Yet a handful of men manage to produce hundreds of children worldwide with their semen. For these 'super spreaders', sperm donation is a lifestyle. Although clinics unofficially maintain a blacklist, they do not hinder these mass donors. "They were thrilled with every healthy donor."
In 2017 Anneke will receive an unexpected phone call: the doctor who had helped her conceive through a donor eight years earlier is on the line. The doctor tells her that her donor is Jonathan, who is in the news at the time because he had produced as many as 102 children through sperm donations to Dutch clinics.
At the time, her practitioners assured Anneke that a maximum of 25 children would be born with the sperm from her donor. But Jonathan's claim that he didn't donate anywhere else turned out to be false. Jonathan had visited almost all Dutch clinics.
Jonathan is now on an unofficial blacklist of fertility clinics. He is one of a handful of men who deliberately cross legal boundaries and have produced (much) more children than the law allows. The blacklist is unofficial, because under applicable privacy laws, clinics are not allowed to exchange information about their donors, but it was born out of necessity.
A preventive system to thwart 'serial sperm donors' has still not been set up. To this day, Dutch clinics only ask a sperm donor to sign a statement stating that he has not previously donated to another clinic and will not do so. Jonathan has signed at all clinics.
